SPECIFICATION forming part of Letters Patent No. 553,949, dated February 4, 1896.

Application filed October 4, 1895. Serial No. 564,587. (No model.)

The bed-plate e of each of the jacks E is fitted to a lateral slideway If in the bed I) on the spider-frame B, along which it is free to reciprocate. From the bedplate e is forwardly projected a downwardly-bent finger e which engages a segmental groove 6 formed upon the periphery of the vertical block 6 which is mounted upon and reciprocates with the shaft e.

The above-described arrangement is such that during a portion of the rotation of the spider-frame B the finger c is in engagement with the segmental groove e and the bedplate 6 is reciprocated along the way b by the reciprocation of the shaft e fland as the spiderframe B is further rotated (the block e having no motion of rotation) the finger 6 dis engages itself from the groove 6, and, during the rest of the rotation of the spider-frame B, the posit-i011 of the bed-plate c is not changed by any reciprocation of the shaft e.

The shaft 6 extends through the journal I) of the spider-frame B which is centrally chambered to receive the same, forming a bearing and support therefor in which the shaft e is free to reciprocate longitudinally, being guided and held in position thereby. To the shaft 6 by the pivotal slotted connection 0 is connected a swinging lever e fulcrumed at e upon the frame A, and which intermediately carries a cam-roll e", which works in a cam-path e upon the cam-wheel 6 which is mounted upon and rotates with the shaft Z). The throw of cam-path e is such that by means of the lever 6 it imparts to the shaft 6 a motion of longitudinal reciprocation which moves the plate 6 and its jack E along the lateral ways from a position un der its form D, substantially as shown, to a position wholly or partially removed from beneath the form convenient for the removal or adjustment of a shoe thereon, and thereafter returns the plate e and its jack E to their original position. The cam e is so formed and timed with reference to the mechanism for rotating the spider-frame B and the mechanism for bringing the forms D D, &'e., into a position of clearance that the lateral movement of each jack, as above described, occurs while its form is in a position of clearance,

and preferably as the jack approaches and 6. The block 6 is free to slide along the sleeve 2, but is held from rotation about the same by a feather 3, which engages a featherway in the block 9 From the shaft e is projected a short arm at, which supports in suitable bearings a rod 5, the inner portion of which is threaded and engages a threaded bearing in the block a. An operating-handle 6 maybe conveniently provided, by means of which the rod 5 may'be rotated and the block 6 moved in either direction along the sleeve 2. It is desirable to note in this con nection that the arrangement of the groove e is such that each of the fingers c engages the same in turn and remains in engagement therewith while its jack is reciprocated by the cam 0 and it is to be further stated that, as shown in the drawings, each of the fingers e engages the groove after the form has been returned to such position, each finger e remaining in engagement with the groove 8 while its form is clear of its jack, an arrangement which insures the finger e being in position to engage the groove 6 as the spider-frame B is rotated. As before stated, the fingers e engage the groove c in turn as the spider 13 rotates, and it may be unnecessary to add that only one of the fingers e is in engagement with the groove e" at any time.

As already stated, the forms D D, 850., have a vertical motion from a position of pressure to a position. of clearance, and vice versa. I would say in this connection that by a position of pressure, as the term is herein used, I mean that position of the form with reference to its jack which the form assumes when the sole of a shoe, mounted upon the jack, is being compressed in the operation of laying the same, and by a position of clearance is meant that position which the form assumes with reference to its jack to allow the jack to be moved with a shoe thereon from beneath the jack to a position convenient for the re moval of the shoe therefrom.

To impart the movement above defined to the forms D D, &c., I have adopted the following mechanism, but I wish to say that, in the specific form described, it constitutes no essential feature of the present invention, and the same result may be secured in other ways without any departure therefrom.

Each of the forms D D, &c., is secured to a vertical movable form-carrier (Z, which, as shown, is held in position by the guides d d d cl (only two shown) on the arms of the spider-frame B, along which the carrier (Z is free to reciprocate radially to the spiderframe. To the carrier (1 are secured a series of springs d d (1 the, (two shown,) which are secured also to the spider-frame B, and which act to approximate the carrier (Z thereon, and the other by the laterally and to the hub Z), and hence to force the form D down upon its jack E or a shoe placed thereon. From opposite sides of each of the carriers D project the cam-rolls (1 01 which are arranged to engage the camways d 01*, one of which is supported by the frame A or a suit-able bracket downwardly extending arm a, rigidly projected from the frame A. The above-described arrangement is such that as the spider-frame B is rotated the rolls d d enter the camways d (1 when their form D is ina position of pressure, and traveling up the cam ways 01 d raise the form D to a position of clearance. As the rotation of the spiderframe 13 continues, the rolls (1 61 travel down the camways (Z 01 allowing the form D to be brought in contact'with a shoe on the jack and finally disengage themselves from the camways d (1 leaving the form D in a position of pressure during the rest of the rotation of the spider-frame. I would say in this connection that I have connected each of the forms D D, &c., with its carrier (Z by a pivotal connection 61 which is located near the center of the form, and allows the form to tip longitudinally to adjust itself to the work. The camways d d are so formed and arranged with reference to the earn (2 and the mechanism for rotating the spider B that the devices controlled thereby perform their f unction in due relation order.

In connection with my present invention I have provided a stop mechanism whereby the rotation of the spider and lateral movement of each jack is stopped automatically when each jack is in a convenient position for the removal of a shoe therefrom. A convenient form of such mechanism is described as follows: r

7 represents a transverse shaft, free to rotate in suitable bearings in the frame A, and to which power may be applied by a belt on the pulley 8 or other suitable means. The shaft 7 carries a worm 9, which engages the worm-gear 10 on the shaft b. On the hub of the gear 10 are formedthe laterally-projected teeth 11, which are adapted to engage with the teeth 12 on a sleeve 14. The sleeve 14 is splined to the shaft b being arranged to rotate therewith and free to slide along the same. A spring 15, preferably coiled around the shaft 19 and bearing against a suitable collar 16 thereon, normally acts to keep the teeth 11 and 12 in engagement, so that the shaft b rotates with the gear 10. From the sleeve 14 is laterally projected a pin 18, which, as the sleeve 14 rotates, engages the wedge 17 and moves back the sleeve 14 against the tension of the spring 15, disengaging the teeth 11 and 12 and stopping the rotation of the shaft As shown in the drawings, the diameter of gear b is four times the diameter of gear b so that a single pin 18, upon the sleeve 14, stops the spider B at every quarter-turn, which, in

rotation of the rod 19 turns the wedge 17 out of the way of the pin 18, and allows the spring 15 to advance the'sleeve 14-until the teetlrll and 12 engage.

A suitably-placed spring (not shown in the drawings) may be conveniently provided to raise the treadle 20 and bring the wedge 17 in the path of the pin 18.

The operation of the present invention is described as follows: WVhen the machine is The rod 19 carries a crank-treadle 20, by means of which it may be rotated. A

at rest, one of the jacks E is presented to the operator, being wholly or partially out from beneath its form D, which is in aposition of clearance. The finger 6 associated with the exposed jack is engaged by the segmental groove 12, and the rolls (1 d of its form-carrier d are engaged by the camways d d. All the other jacks are beneath their respective forms, which are in a position of pressure. The operator places 'a shoe upon the jack which is presented to him and starts the rotation of the spider-frame B by depressing the treadle 20. As the rotation of the spiderframe B commences, the shaft e moves i11- ward, carrying the jack E under its form D, which has been held for that purpose in a position of clearance, the rolls d d having traveled over a circular portion of the camways 01 d (See Fig. 4.) Then the jackE is in position under its form D the rolls (Z d have traveled over the circular portion of the ways d d and move inward along the same, allowing the springs 61- (1 d d to force the form D downward into a position of pressure. When the form D is in a position of pressure, the rolls (Z d disengage themselves from the camways d and the finger e from the groove 6 and the jack E is left under the pressure of its form for the rest of the rotation of spider B. As the rotation of spiderB continues, the finger e on the next jack E enters the groove 6 and the roll (1 d on its form-carrier d enters the camways d (1 As the rolls d d enter the ways 01%? they are forced outward against the tension of the springs 01 d 01 d bringing the form D into a position of clearance, when the shaft 6 is again advanced, moving the last E out from beneath the form D and presenting it to the operator in a convenient position for removal or adjustment of a shoe, when the rotation of spider-frame B and the lateral movement of last are stopped by the pin 18 coming in contact with the wedge 17, as hereinbefore explained.

The operation above described may be indefinitely repeated, the operator removing the finished work and adjusting new work as I each jack is presented to him and depressing the treadle to start the machine.

I would say that I am aware of the state of the art as shown in Letters Patent to Coy and Paul, September 0, 1890, No. 436,034, also to Coy, January 10, 1888, No. 376,406, and C011- yer, June 1-3, 1876, No. 178,598, all in the class of sole-machines, and I claim nothing shown therein. I am not, however, aware that it has heretofore been proposed to construct a solelay'ing machine embodying a rotary carrier and movable jacks and forms mounted thereon in which the three essential movements of pressure, clearance, and presentation of the jacks to the operator have been accomplished automatically.

I therefore claim as novel and desire to sccure by Letters Patent 1. In an organized sole-laying machine the combination of a rotary carrier, a series of pressing-forms mounted upon the carrier, a series of shoe'supporting jacks, associated respectively with the pressing-forms, mounted upon the carrier and movable transversely to the plane of its rotation, and connected mechanisms, operating automatically to produce compression and clearance between each form and its associating jack, and to rotate the carrier and actuate the jacks, whereby one jack is presented to the operator in convenient position for the removal of a shoe therefrom, while the other jacks remain under pressure, substantially as described.

2. In an organized sole-laying machine the combination of a rotary carrier, a series of pressing-forms mounted upon the carrier, a series of shoesupporting jacks, associated respectively with the pressing-forms, mounted i in suitable transverse guideways upon the 1- carrier, along which they are free to reciprof cate transversely to the plane of the rotation of the carrier, said guideways, and connected mechanisms operating automatically to produce compression and clearance between each form and its associated jack, and to rotate the carrier and actuate the jacks, whereby one jack is presented to the operator in convenient position for the removal of a shoe therefrom while the other jacks remain under pressure, substantially as described.

3. In a sole-laying machine the combination of a rotary carrier, a series of pressingforms mounted upon the carrier, a series of shoe-supporting jacks, associated respectively with the pressing-forms, mounted upon the carrier and movable transversely to the plane of its rota-tion, means for producing compression and clearance between each jack and its associated form, means for rotating the carrier, and mechanism common to all the jacks for independently actuating each jack, substantially as described.

4. In an organized sole-laying machine the combination of a rotary carrier, a series of pressing-forms mounted upon the carrier, a series of jacks mounted upon the carrier each arranged to co-operate with a form and movable out of operative relation thereto, and connected mechanisms, operating automatically to produce compression and clearance between each form and its associated jack, to rotate the carrier, and to actuate the jacks, substantially as described.

Witness my hand, in the presence of two attesting witnesses, this 2d day of October, 1805.
